Abstract

The invention relates to public network conversation and private network conversation interconnection gateway equipment, comprising an interconnection gateway casing; the front side panel of the interconnection gateway casing is provided with a display control unit and a local voice interface; the interconnection gateway casing is internally provided with a power supply management module and a circuit board; the circuit board is provided with a signal processing module, a simulation conversation processing module, a digit conversation processing module and a public network fixed telephone interface module. The simulation conversation module comprises a filter, an automatic gain control device and a VOX device; the digit conversation processing module comprises a digital filter and a coding and decoding device; the public network fixed telephone interface module comprises a CDMA module, a GSM module and a fixed network module. The public network conversation and private network conversation interconnection gateway equipment employs a surfing interconnection gateway to combine a private network and a public network, solves the problem of lack of private network coverage, and employs a public network conversation terminal as a supplement to private network large scope communication under the condition of neither changing nor eliminating an original system.

Description

technical field [0001] The invention relates to the field of network intercom technology, in particular to an intercommunication gateway device for public network intercom and private network intercom and an application method thereof. Background technique [0002] At present, the two intercom networks include private network intercom communication and public network intercom communication. The private network intercom communication system mainly refers to the self-built relay station system, which has the advantages of safety and stability, high connection rate, and is not easily affected by network fluctuations. . However, the system is limited by the number of base stations, building blocks, etc., and its coverage is limited, making it impossible to intercom in suburban counties and remote areas. [0003] Public network intercom is a dedicated mobile communication system for command and dispatch established on the basis of China Telecom's CDMA mobile communication networ...
